Sargun Dhillon a3f933d998 Fix permission denied warnings during tests (#617)
For some reason the kubelet tries to do things that it gets perm
denied. This changes the base.yml in the skaffold file to have
the permissions. In turn, this broke the node deletion test. So,
instead of looking for the deletion event (imperative), we wait
for the node UID to change (declarative).
